INDEX-CARD.

Speccation 0f Letters Patent. Patented June 28, 1921.

Application led February 1, 1919. Serial No. 274,436.

To @ZZ tti/10m t may concern:

Be it known that I, DAVID E. HUNTER, a

citizen of the United States, and a resident of Muskegon, in the countyof Muskegon and State of Michigan, have invented certain new and usefulImprovements in Index- Cards, of which the following is a specification.l

My invention relates to index cards and particularly to improved indexinsert supporting construction for such cards. Index cards usually havean extension or tab at their upper edges and the object of my inventionis to provide a strengthening cover for such tabs, such covering beingpreferably of transparent material and provided with a space or pocketinto which may readily be inserted a tablet or strip on which is printedindex or other information which Vcan be read through the transparentwall of the pocket.

On the accompanying drawing cards arel shown to which my invention isapplied. On this drawing- Figure 1 is an elevational view of an in dexcard with one form of index tablet holder applied. f

Fig. 2 shows a section of the card in rear elevation. y

Fig. 3 is an enlarged sectional view on plane 3-3 Fig. 1. c

Fig. 4 is a similar sectional view showing the manner of withdrawing atablet.

Fig. 5 shows a section of a card with1 a modified form of tablet -holderapplied thereto.

Fig. 6 is a plan view of a tablet to be used in the construction of Fig.5.

On the drawing, 10 represents the index -card which at its upper edgehas the extension or tongue 11. A section of this tongue is cut out toleave a rectangular recess, and a piece of transparent material such ascelluloid is folded and applied over the recessed portion of the tongueand the adjacent part of the card body to form a pocket 12 and astrengthening Covering 13 for the tab, as well as front and rear sidesof the pocket-12, the transparent material being intimately cementedagainst the front and rear faces of the tongue and card and being cut atits ends to follow the contour of the tongue.

,Ihe rear side ef the covering 13 is eut in blank so that when thecovering is applied to .the card, there will be the rectangular open-Ing 14 in its rear wall which opening exposes the section 15 of theindex card and also lower part 16 of the pocket 12. This open lower part16 of the pocket enablesinsertion into the pocket of an index tablet 17,the Celluloid above this open end being sufficiently elastic to yieldduring insertion of the table. When the tablet has been fully inserted,its lower end will drop into the pocket and its lower edge will abutagainst the lower edge of the pocket and the celluloid will hold thetablet in this position. To facilitate the withdrawal of the tablet, thenotch 18 is provided in the card just below the pocket so that the endof an instrument, such asv the tweezers t may be inserted under theexposed lower end of the tablet and the tablet caught and withdrawn fromthe pocket as indicated in Fig. 4.

In Figs. 1 and 2 the tablet receiving pocket 75 extends to the upperedge of the tongue 11. In the arrangement of Fig. 5 the pocket 19 iselliptical and is below the upper edge of the tongue in order to leavethe abutment section 20 for the elliptical tablet 21 shown 80 in Fig. 6.In the back of the Celluloid covering 22 is cut the crescent shapeopening 23, which overlaps the lower end of the pocketV 19 and part ofthe index card. The celluloid tongue 24 is sutlicientlyexible so that 85it can be raised a trifle to allow the tablet to be readily slipped intothe pocket and below the pocket notch 25 is provided in the card for theinsertion of the withdrawing instrument, as the tweezers t.

The covering 13 folded intimately around the card tab edge and cementedto the tab and Cardl surfaces materially strengthens and stiffens theseparts and at the same time forms a transparent inclosure for the indextablet, strip or other insert. The covering material is preferablyv awaterproof, transparent material such as Celluloid and can therefore bereadily wiped or washed clean to leave the information on the insert atall times fully and clearly visible. I do not desire to be limited tothe exact construction and arrangement herein described,.as modiicationsare no doubt possible which would still come within .the SCOpe of theinvention.

I claim as follows: V l An index card having a portion near an edgethereof cut out to leave a recess, transparent material folded aroundthecard edge A trance slot for the insertion of an index 1Y0 tablet intothe pocket, said exposed card seotion below said slot being notched forthe e accommodation of an implement for withdrawing the tablet from ,thepocket.

In witness whereof I hereunto subscribe l5 my name this 29 day ofJany.,A. D. 17919.

DAVID E. HUNTER.
